Attack FX R is a badge in Paper Mario: The Thousand-Year Door. It can be found in Hooktail Castle, inside a jail cell accessible by using Mario's paper form. If Mario equips the badge, the sound of a cricket's chirp plays whenever Mario swings his hammer outside of battle and whenever he attacks an opponent during battle with his jumps or his hammer. Before the badge is even obtained, it is first alluded to in a letter from Kolorado's father, saying that Hooktail fears something "that begins with 'cr' and ends with 'icket'". During the battle against Hooktail, if Mario attacks with the badge equipped, Hooktail exclaims her distaste for the badge, and her attack and defense are both lowered by one (to a minimum of one and zero, respectively) every time Mario attacks and the sound effect plays. Outside of the battle against her, the badge has no effect. If multiple Attack FX badges are equipped, the sound effects play one at a time.
